(54) Water storage tank


(57) Disclosed is a water storage tank (100) capable of preventing water from being discharged through an air discharge path configured to facilitate the flow of water. The water storage tank includes a tank body (200) including an inlet (P) and an outlet, a first outlet pipe (300) provided in the outlet of the tank body such that one side of the first outlet pipe is placed outside the tank body while the other side thereof is placed inside the tank body, and a second outlet pipe (400) having one side connected to the other side of the first outlet pipe such that air or water existing in the tank body is discharged to the outside. Accordingly, the flow of water into the water storage tank can be facilitated, water can be discharged by water inflow pressure, and no water is discharged through an air discharge path when water stored in the water storage tank is discharged by water inflow pressure, thereby obviate the mixing of water from the outlet pipe with water from the air discharge path. Thus, water having a temperature desired by a user can be provided.
